This rugged metal column was designed specifically for the determination of free and total glycerin in B100 biodiesel samples.
Features and benefits of this column include: • Metal is used as the column material, virtually eliminating accidental column breakage during handling• Metal columns do not require a coating to provide strength (NOTE: the protective polyimide coating on the outside of fused silica columns slowly burns off at 380 °C, exposing bare fused silica which is fragile and susceptible to breakage)• Includes a guard that both protects the analytical column from excess reagent and non-volatile compounds, extending column life, and acts as a retention gap, minimizing peak broadening • The guard is an integrated guard, thereby providing protection with a leak-free connection ...Read more

Description

This rugged metal column was designed specifically for the determination of free and total glycerin in B100 biodiesel samples.

Features and benefits of this column include:

• Metal is used as the column material, virtually eliminating accidental column breakage during handling• Metal columns do not require a coating to provide strength (NOTE: the protective polyimide coating on the outside of fused silica columns slowly burns off at 380 °C, exposing bare fused silica which is fragile and susceptible to breakage)• Includes a guard that both protects the analytical column from excess reagent and non-volatile compounds, extending column life, and acts as a retention gap, minimizing peak broadening • The guard is an integrated guard, thereby providing protection with a leak-free connection (the guard and analytical column are one continuous piece of tubing; there is no union between the guard and analytical column) • Low bleed characteristic, even at 380 °C • Provides good peak shape and resolution for all glyceride impurities of interest • Able to separate glycerin in addition to mono-/diglycerides (as methyl esters) plus triglycerides from the FAMEs • A maximum temperature of 380 °C (isothermal) and 430 °C (programmed) exceeds the temperature limitations specified in biodiesel methods such as ASTM D6584 and EN 14105
